These colonies were characterized by a large aggregation of adult bats ranging between a few hundreds to few thousands. The most remarkable colony was noted at Targol, where ~11,000 bats of mixed age groups (young ones, juveniles and adults) roosting on various ten species of 182 large tall trees. It is now considered as one of the largest ever recorded roosting colonies of Pteropus giganteus in Gujarat State and may be in India as well. Key Words: Indian flying fox Pteropus giganteus, roost, colony, Jambughoda Wildlife Sanctuary. Introduction: The order Chiroptera is the second largest order of Class: Mammalia, that comprises about over 1117 species of bats in which the suborder Megachiroptera contains one family (Pteropodidae) that includes 186 species of mainly frugivorous bats (Simmons 2005). India has 13 species of fruit bats (Bates and Harrison 1997, Image 1: The map showing location of Jambughoda Wildlife Sanctuary with Srinivasulu et al. 2010) but only State of Gujarat and location sites of colonies of Indian Flying Fox recorded three are common and found in and out of the Sanctuary. throughout the country, they include Indian flying fox (Pteropus This species is a social and congregations of this species have giganteus), Fulvous fruit bat polygynandrous (promiscuous), been so far recorded at (Rousettus leschenaultii) and living in large aggregations as Peradeniya Botanical Gardens Short-nosed fruit bat (Cynopterus colonies. Their diurnal roosts are near Kandy, Sri Lanka in sphinx). The remaining species found in various types of large September 2002 by Krystufek are rare and have restricted and tall trees, including Ficus (2009). This is one of the most distribution.

It covers an area of 130.38 km² of forest within an altitudinal range from 230 to 354 m above sea level. The forest can be classified tropical dry deciduous type (Champion and Seth 1968). The flora and fauna of the sanctuary is moderately rich and diversified with a total of 17 mammalian species inhabitants (Pandya and Oza, 1998; Devkar et. al., 2013). Methodology: The bat census method was partially adapted here as mentioned by Krystufek Image 2: Spatial distribution congregation and roosting of Indian flying (2009). Each tree was plotted foxes (Pteropus giganteus) in Targol (Jambughoda Wildlife Sanctuary) site within 20 × 20 m squares.
